|The dedicated VRAM is 64MB. This is an actual physical memory chip that is used by the graphics & graphics only. Any other graphics memory being reported is shared memory which is borrowed from the main system memory on an as-needed basis. This is called "dynamically allocated shared memory".|
The amount of video memory isn't as important the graphics chip (GPU) that uses it. If the graphics chip is weak/low end, having more graphics memory will do very little to improve graphics performance. Does your question have to do with gaming performance or the ability to play games on your laptop? How about posting the make/model?
